[. . . ] It is sure to become a valuable tool because you will always have sharp drill bits before a project, during a project, and after a project. As president of this company, I am very proud of the quality of our products--and I am equally proud of the great people at Drill Doctor® who design and produce them. If you have questions or need help with your Drill Doctor®, please contact us and one of our customer representatives will be there to help. Use this User's Guide and the DVD video to learn to operate your Drill Doctor® quickly and easily. [. . . ] If the machine quits removing material before the chisel is clean, realign and sharpen again. (Model 750X users can increase or decrease MTO (material take-off) to speed up this process. Leave bit in Chuck after sharpening Always align and sharpen a bit before splitting it. To split the point, do not remove the bit from the Chuck after sharpening. If one side of the bit is undersplit, insert the Chuck into the Splitting Port again and split both sides. Repeat until the split sides are equal and look like the correctly split bit shown above. Align one of the Sharpening Guides on the Chuck (short white marks) with the Splitting Guide on the Splitting Port. Make sure the Alignment Guides insert into the Split Point Guide Rails in the Splitting Port. Not enough material has been removed from the Heel of the drill bit. Check the tip of the bit carefully to determine that both sides of the bit are split equally. Split lines are joined in the center and Chisel Edge has been removed. Reinsert the chucked bit into the Sharpening Port and remove enough of the tip until the split tip looks like the correctly split bit above. The Grit Tube attachment is designed to keep any sparks caused by sharpening safely inside the machine and away from you. in addition , the Grit Tube reduces the sharpening dust in the air and on your workbench. Simply insert the Grit Tube into the Splitting Port of your Drill Doctor when sharpening. Clean the inside of your Drill Doctor and the Grit Tube on a regular schedule. The grit tube is designed to accept a standard 1" shop vacuum for extended periods of sharpening. It may take two or three complete sharpenings (repeat all steps) to resharpen a very dull or chipped large drill bit. Your Drill Doctor is delivered with a 180-grit Diamond Sharpening Wheel. If you regularly sharpen larger bits between 1/2" and 3/4", you may wish to purchase the coarser 100-grit Diamond Sharpening Wheel, which sharpens larger bits faster. Short Drill Bits and Bits Smaller than 1/8" set the point angle for 118°. Put the bit in the Chuck as normal, but tighten Chuck so that it is just snug enough for the bit to move freely. [. . . ] The Diamond Sharpening Wheel may need to be changed if: · Sharpened drill bits burn or turn blue no matter how fast or slow you rotate the Chuck. When touching the Sharpening Wheel (with the machine unplugged), the lower portion feels too smooth (nonabrasive). When sharpening the drill bit, it takes too many halfturns to sharpen. You can change the degree angle of any drill bit from 135° to 118°. [. . . ]
